Figure 5 - 4-Person Temporary HLL with EALs
Minimum Fall Clearance (Three or Four Workers)
* 7’ Freefall Distance scenario is only allowed when the FallTech 4-Person Temporary HLL is attached to the FallTech SteelGrip
®
Stanchion.
Freefall should be limited to 6’ or less when used with any other anchorage connector.
When a worker falls while connected to the horizontal lifeline, the system will deflect. If two or more workers are connected to
the same horizontal lifeline, and one worker falls, the other workers may be pulled off the walking-working surface. The poten
-
tial for the other workers falling increases as the lifeline length increases. The use of independent HLL systems for each person or
shorter span lengths is recommended to minimize the potential of the other workers falling.
